Penggunaan Silica Fume Sebagai Substitusi Semen Dengan Bahan Tambah Abu Pecahan Karang Pada Beton

Abstract: Silica Fume merupakan material pozzolan yang sangat halus, dimana mengandung komposisi silika lebih banyak dari sisa produksi silicon atau alloy besi silikon. Silica fume yang digunakan berbentuk bubuk sebagai substitusi semen. Penelitian ini bertujuan untuk mengetahui pengaruh persentase yang menggunakan silica fume sebagai substitusi semen dengan bahan tambah abu pecahan karang terhadap kuat tekan, kuat tarik belah dan modulus elastisitas beton. Penelitian ini metode SNI (f’c) 30 MPa dan sampel bentukan sili… Show more
